Android(安卓)SearchView

项目需要实现Search功能，根据网上的一些文章和Android的文档，自己实现了一个搜索联系人的。测试手机为三星的

无图无真相

代码如下：

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context=".MainActivity" >    <SearchView        android:id="@+id/search"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="#F0F0F0F0" />    <ListView        android:id="@android:id/list"        android:layout_width="match_parent"        android:layout_height="0dip"        android:layout_weight="1" /></LinearLayout>

searchable.xml，这个文件至关重要，可以配置搜索模式，比如voicesearch，用于链接到设备的全局搜索。如果不希望加到全局搜索，可以不配置这个文件。

<?xml version="1.0" encoding="utf-8"?><searchable xmlns:android="http://schemas.android.com/apk/res/android"    android:label="@string/contactsList"    android:hint="@string/searchHint"    android:searchMode="queryRewriteFromText" />

Androidmanifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.demo.contactsearch"    android:versionCode="1"    android:versionName="1.0" >        <uses-permission android:name="android.permission.READ_CONTACTS"/>    <uses-sdk        android:minSdkVersion="17"        android:targetSdkVersion="18" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.demo.contactsearch.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>            <intent-filter>                <action android:name="android.intent.action.SEARCH" />            </intent-filter>            <meta-data                android:name="android.app.searchable"                android:resource="@xml/searchable" />        </activity>    </application></manifest>

MainActivity.java

package com.demo.contactsearch;import android.app.Activity;import android.content.Context;import android.database.Cursor;import android.os.Bundle;import android.provider.ContactsContract;import android.provider.ContactsContract.RawContacts;import android.view.Menu;import android.view.inputmethod.InputMethodManager;import android.widget.ListView;import android.widget.SearchView;import android.widget.SearchView.OnQueryTextListener;import android.widget.SimpleCursorAdapter;public class MainActivity extends Activity {private SearchView mSearchView;private ListView mListView;private SimpleCursorAdapter mAdapter;private Cursor mCursor;static final String[] PROJECTION = new String[] {ContactsContract.RawContacts._ID, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY };@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mCursor = getContentResolver().query(RawContacts.CONTENT_URI, PROJECTION, null, null, null);mAdapter = new SimpleCursorAdapter(this,android.R.layout.simple_list_item_1, mCursor,new String[] { RawContacts.DISPLAY_NAME_PRIMARY }, new int[] { android.R.id.text1 },0);mListView = (ListView) findViewById(android.R.id.list);mListView.setAdapter(mAdapter);mSearchView = (SearchView) findViewById(R.id.search);mSearchView.setIconifiedByDefault(true);mSearchView.onActionViewExpanded();mSearchView.setFocusable(false);mSearchView.clearFocus();//mSearchView.setIconifiedByDefault(true);mSearchView.setOnQueryTextListener(new OnQueryTextListener() {@Overridepublic boolean onQueryTextChange(String queryText) {String selection = RawContacts.DISPLAY_NAME_PRIMARY + " LIKE '%"+ queryText + "%' " + " OR "+ RawContacts.SORT_KEY_PRIMARY + " LIKE '%" + queryText+ "%' ";//String[] selectionArg = { queryText };mCursor = getContentResolver().query(RawContacts.CONTENT_URI, PROJECTION, selection, null, null);mAdapter.swapCursor(mCursor);return true;}@Overridepublic boolean onQueryTextSubmit(String queryText) {if (mSearchView != null) {InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);if (imm != null) {imm.hideSoftInputFromWindow(mSearchView.getWindowToken(), 0);}mSearchView.clearFocus();}return true;}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}
